Service Tag: LMBD 457-0
Type: Smart AI
Appearance: A male Sangheili clad in a Field Marshall armor, usually sporting a Carbine (Blood of Suban). Can float around at will, with a limited radius around the chip and has a blue aura, much like the AIs in RvB. His voice produces echoes as he speaks. Has green eyes, but the blue aura makes it hard to notice. Has small minor Lambda symbols in the left shoulder and chest armor.
Personality: Serious (due to his Sangheili appearance) with a mixture of sarcasm, but also has a human attitude and humor. Has a strange obsession with the "λ" symbol.
Lambda is a prototype smart AI which aims into incorporating Forerunner technology to further increase it's capabilities and lifespan. Has been in development since 2486, but was only deployed in 2551, precisely in March 15th due to difficulties with the technology, which were eventually understood and mastered in the underground lab located beneath the ice platform near ONI Sword Base in Reach. The engineers responsible did not survive the Fall of Reach.
Many prototypes came, but failed. The eleventh prototype was the first to succeed, which gave it the temporary name of "Lambda". However, since the AI had an odd obsession with the symbol, it became it's official name.
First assigned to Wolf Team, a group of S-IIIs, for testing, results have shown incredible abilities, such as near to no effort in hacking into Covenant devices and networks and Forerunner terminals, far superior than earlier smart AIs. His capabilities would still be upgraded as testing proceeded to ensure it is the best AI it could possibly be. It's first real assignment, however, was held during the Fall of Reach.
Assigned to Epsilon Team, another group of S-IIIs and MCPO John-387, a Spartan-II, as well as dozens of Marines and ODSTs, the mission was to capture a CCS-class Battlecruiser in order to give a possible beginning to Operation: RED FLAG.
Unfortunately, it seems that the cruiser was actually expecting a boarding party and had set up effective defenses across all hangars, and the following battle would quickly turn into a blood-bath as more of our forces fell than theirs.
Since capturing the ship was then deemed impossible, there was immediate orders to retreat. However, the Spartan-II was convinced that it would still be possible to arm a SHIVA nuke to destroy the ship. With the phenomenal assistance of Lambda, he was successful with arming it and retreating. The AI remotely detonated the nuke when in safe range and the CCS was successfully destroyed. With Reach inevitably falling and nowhere to run, John and Lambda rushed to CASTLE Base.
Since then, Lambda had been with John, assisting him in every mission and operation. But as the Created rose to power, the Spartan got dubious of his companion, fearing for betrayal, but that request was quickly refused, even when given complete opportunity. Part of this refusal was due to Lambda's relationship with the Spartan, as they've been inseparable since '52.
- A twin AI started development shortly after it's success in the same laboratory, named "Mi" as to follow suit with the greek alphabet, but it was put on halt when Reach was invaded and subsequently destroyed when the ice platform above the lab shattered.
